Shoe and boot pasting presses, for instance such designed as tablepresses or as rotary ones, are equipped with a plurality of individualpressing devices or pasting molds arranged around an axle so designed asto constitute also a kind of valve through which an agent underpressure, especially compressed air can be conducted to said individualdevices or molds. In order to render possible a continuousafter-examination of the height of the pressure existing in theindividual molds, viz. after every mold with the pressure therein hasbeen disconnected from the source or supply of the compressed air, orthe like, pressure gauges are provided, that is to say, a separate gaugeis provided for every mold, but as this means the provision of as manygauges as there are molds the pasting press becomes very expensive and,besides, the many gauges are often times in the way and give rise totroubles.

The present improved pasting press is distinguished from theabove-mentioned older pasting presses, and excels them, by the featurethat there is, in general, only one pressure gauge which is, thus,common to all pressing molds. Anyhow, it is nevertheless possible toprovide more than only one pressure gauge between the place where thepasting is effected and the place where the mold with the pasted shoe orboot is withdrawn whereby it is rendered possible toexamine severaltimes the height of the pressure in the pasting device just beingtreated. In general it will, however, be suflicient to operate with onlyone pressure gauge in order to ascertain whether the pressure existingwithin the mold concerned is maintained inthe proper height from thepasting place to the withdrawal place.

The invention is illustrated diagrammatically and by way of example onthe accompanying drawing on which Figure 1 is a vertical section througha rotatory pasting press designed as a table press for the reception ofa comparatively large plurality of circulating pasting devices carriedby the table, this latter with the pasting devices being omitted in thefigure, and Figure 2 is a plan of the machine, the uppermost portion,viz. the rotatory valve visible on the top of Fig. 1, being omitted.

On the drawing, b denotes a circular disk or plate which is to receiveand carry round the above-mentioned table with the pasting devices ormolds thereon (not shown, as already mentioned), and a is a tubularsleeve extending upwardly from said plate b and surrounding a stationaryaxle around which it can be turned together with the said table etc. Thedisc b may be driven around in known manner mechanically or by foot stepby step. Attached to the upper end of said axle is a valve body 11designed as a truncated cone, and on said body is a rotary casing ehaving as many radial bores or passages f as there are pressing molds.The plate I) and said casing e are turned simultaneously and with equalspeed by suitable means (not shown) and while thus being turned thepassages ,f of the casing e communicate successively with one end of aradial bore g provided in the body d and communicating at its other endwith a pressure gauge h which is the only one gauge pertaining to themachine in the example shown, and the object of which is to indicate thepressure existing within every individual mold just communicating withthe passage 9 at the time being.

The compressed air or other agent under pressure exerting the pressurewithin the individual consecutive molds or pasting devices is suppliedthrough a channel 9 of the axle c. This channel communicates withpassages k and I (Fig. 2) likewise provided in the body d andterminating also at the circumferential surface of this body so as tocommunicate successively also with that passage 1 which is the next tocommunicate with the passage g and the gauge h. There is, furthermore,in the body it a channel 2' which is the escape channel becoming activewhen the pasting operation has been finished and the respective pastingdevice or mold arrives at the place of withdrawal.

The operation phases are the following: First, a preliminary pressure issupplied through the passage k, then the full pressure is suppliedthrough the passage Z; this pressure is maintained within the respectivedevice or mold while this is being moved from the passage 1 to thepassage 9, and can be read at the pressure gauge h. Finally, the moldconcerned comes into communication with the passage i, which is therelief valve through which the compressed air can escape from the saidmold. In this way'the consecutive individual molds or pasting devicescommunicate successively with the passages k, l, g and i.

I claim:

1. A shoe and boot pasting press for use in connection with a pluralityof circulating individual pasting devices or molds to be moved from apasting place to a withdrawal place, comprising, in combination withsaid devices or molds, means for supplying an agent under pressure tothe consecutive pasting devices or molds at the pasting place; means forrelieving the said devices from the pressure at the withdrawal place, apressure gauge for use in connectionrwith all pasting devices or moldsand for after-examining the pressure existing in the said devices ormolds while these are being moved from V the first-mentioned place tothe place mentioned in the second case, and means for'establishing acommunication of the pasting deviceor mold concerned at the time beingwith said pressure gauge. 7

2. A shoe and boot pasting press foruse in connection with a pluralityofcirculating individual pasting devices or molds to be moved from apasting-place to a withdrawal place, comprising, in combination withsaid devices or-molds, a central valve connected with a supply for anthe first-mentioned place to the place mentioned l5 gauge.

agent under pressure; means for supplying said agent from said valve tothe pasting device or mold just present at the pasting place; means forrelieving that pasting device or mold from the pressure within it priorto arriving at the withdrawal place by the intermediary of the saidvalve; a pressure gauge for use in connection with all'pasting' devicesor molds and 'for afterexamining the pressure existing in the saiddevices or molds while these are being moved from in the second case,and means for establishing a communication of the pasting device or moldconcerned at the time beingwith said pressure ARNO ERBE.
